static publisher and utf-8 coding

after building a site, we included static publisher. Problems are, that in Menu, fields and on some other places the coding for german "Umlaute" is wrong. It shows exactly what is stored in the db, e.g.:
"ÃƒÅ“ber" instead of "Ãœber" or "GeschÃƒÂ¤ftsfÃƒÂ¼hrer" instead of "GeschÃ¤ftsfÃ¼hrer".
DB collation ist set to utf-8, even the static pages show the correct coding:
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<meta http-equiv="Content-Language" content="de-DE"/>
Any idea where to look to correct this ?
